Technical Field
[0001] The present application relates to the technical field of refrigerator manufacturing, and in particular to a method for processing refrigerator operation data and an after-sales system. Background Art
[0002] A refrigerator is a household appliance commonly used in people's lives. It freezes and refrigerates food through the refrigeration components installed inside to meet people's life needs.
[0003] Refrigeration is achieved by cooling the refrigerant to a temperature below its normal boiling point and maintaining it within a certain low temperature range; based on the principle of compression refrigeration, a certain refrigerant substance is compressed into a high-temperature and high-pressure state through a compressor, and then the refrigerant substance is cooled through a condenser to turn it into a liquid state; then, the refrigerant substance is throttled through an expansion valve to reduce its pressure, and the liquid refrigerant substance evaporates and absorbs heat, thereby lowering the temperature; this process is repeated continuously to achieve a cooling effect.
[0004] In actual use, as the refrigerator ages or is damaged by external factors, the refrigerant in the refrigerator may leak, causing the refrigerator to fail in refrigeration, resulting in user complaints. Summary of the invention
[0005] In order to solve the above technical problems, the embodiments of the present application provide a method for processing refrigerator operation data and an after-sales system.
[0006] Some embodiments of the present application provide a method for processing refrigerator operation data, the method comprising: periodically acquiring the operation data of the refrigerator; calculating time data of the refrigerator during a refrigeration process based on the operation data, the time data comprising at least one of a compressor operation time required for the refrigerator to lower a unit temperature and a defrost cycle of the refrigerator; comparing the time data with preset mapping data, and determining whether there is a refrigerant leak in the refrigerator based on the comparison result; generating refrigerant leakage prompt information when there is a refrigerant leak in the refrigerator, and sending the refrigerant leakage prompt information to a preset after-sales terminal.
[0007] In the above embodiment, based on the periodically acquired operating data of the refrigerator, the time data of the refrigerator's refrigeration process is calculated to determine whether there is a refrigerant leak in the refrigerator based on the comparison result of the time data and the mapping data, and when there is a refrigerant leak in the refrigerator, a refrigerant leak prompt message is generated and sent to a preset after-sales terminal, so that the present application can identify a refrigerator with a refrigerant leak based on the operating data of the refrigerator, and after the after-sales terminal receives the refrigerant leak prompt message, it is convenient for the after-sales personnel to take timely response measures, thereby reducing user complaints.
[0008] In some embodiments of the present application, based on the above technical solution, the time data is compared with the preset mapping data, and whether the refrigerator has a refrigerant leakage is determined according to the comparison result, including: when the comparison result is that the compressor running time required for the refrigerator to lower the unit temperature is greater than the preset mapping time, and / or the defrost cycle of the refrigerator is greater than the preset mapping cycle, it is determined that the refrigerator has a refrigerant leakage.
[0009] In the above embodiment, the present application combines the two judgment methods to judge whether the refrigerator has refrigerant leakage, which can improve the accuracy and reliability of the judgment result and improve the work efficiency of after-sales personnel.
[0010] In some embodiments of the present application, based on the above technical solution, the method further includes: determining the ambient temperature and compartment temperature of the refrigerator according to the operating data; when the difference between the ambient temperature and the compartment temperature is greater than a preset temperature difference threshold, adding a preset time mapping value to the mapping time to obtain an updated mapping time.
[0011] In the above embodiment, in some specific cases, in order to ensure the normal refrigeration effect of the load, the refrigeration control time of the refrigerator needs to be longer than the refrigeration control time under normal circumstances. Therefore, the mapping time is adjusted by a certain increment to reduce the occurrence of misjudgment or misjudgment of refrigerant leakage. Further, when judging a refrigerator with refrigerant leakage, the accuracy and reliability of the judgment result can be improved, thereby improving the work efficiency of after-sales personnel.
[0012] In some embodiments of the present application, based on the above technical solution, the time data of the refrigerator during the refrigeration process is calculated according to the operating data, including: determining the compartment temperature of the refrigerator according to the operating data; calculating the temperature difference between the compartment temperature and a preset target temperature, and obtaining the refrigeration time consumed by the refrigerator to drop from the compartment temperature to the target temperature, and determining the compressor operation time required for the refrigerator to lower the unit temperature according to the ratio of the refrigeration time to the temperature difference.
[0013] In some embodiments of the present application, based on the above technical solution, the time data of the refrigerator refrigeration process is calculated according to the operating data, and also includes: determining the evaporator temperature of the refrigerator according to the operating data; and determining the defrost cycle of the refrigerator according to the change law of the evaporator temperature.
[0014] In some embodiments of the present application, based on the above technical solution, the method also includes: determining the ambient temperature and compressor frequency of the refrigerator according to the operating data, and determining the ambient temperature range corresponding to the ambient temperature, and determining the compressor frequency range corresponding to the compressor frequency; determining the mapping data according to the ambient temperature range and the compressor frequency range.
[0015] In the above embodiment, the mapping data of the present application determines the specific mapping data through the ambient temperature range and the compressor frequency range, which facilitates the rapid finding of the mapping data for comparison with the time data and improves the execution efficiency of the method for processing refrigerator operation data.
[0016] In some embodiments of the present application, based on the above technical solution, the time data of the refrigerator refrigeration process is calculated according to the operating data, and also includes: when the refrigerator is in an open-door state, the compressor operation time required for the refrigerator to lower the unit temperature is reset, and when the refrigerator is in a closed-door state, the compressor operation time required for the refrigerator to lower the unit temperature is calculated according to the operating data.
[0017] In the above embodiment, the calculation of the compressor operation time required for the refrigerator to lower the unit temperature needs to be limited to a certain time period when the refrigerator is closed, so as to eliminate the change in operating data caused by opening the refrigerator door, thereby reducing the probability of the judgment result of refrigerant leakage being affected.
[0018] In some embodiments of the present application, based on the above technical solution, generating refrigerant leakage prompt information when there is a refrigerant leakage in the refrigerator includes: calculating a first difference between the compressor operation time required to lower the unit temperature of the refrigerator and the mapping time, and determining the leakage degree of the refrigerant leakage according to the first difference; determining a first maintenance priority of the refrigerator according to the leakage degree, and the first maintenance priority is used to determine the refrigerant leakage prompt information.
[0019] In the above embodiment, the leakage degree of the refrigerant leakage is determined based on the first difference between the compressor operation time required for lowering the unit temperature of the refrigerator and the mapping time, and the first maintenance priority of the refrigerator is determined according to the leakage degree, so that after-sales personnel can give priority to refrigerators with serious leakage degrees of refrigerant leakage according to the first maintenance priority, which is convenient for after-sales personnel to reasonably plan maintenance work, improve the work efficiency of after-sales personnel, and reduce user complaints caused by untimely maintenance.
[0020] In some embodiments of the present application, based on the above technical solution, generating refrigerant leakage prompt information when there is a refrigerant leakage in the refrigerator includes: calculating a second difference between the defrost cycle of the refrigerator and the mapping cycle, and determining the leakage degree of the refrigerant leakage according to the second difference; determining a second maintenance priority of the refrigerator according to the leakage degree, and the second maintenance priority is used to determine the refrigerant leakage prompt information.
[0021] In the above embodiment, the leakage degree of the refrigerant leakage is determined based on the second difference between the defrost cycle and the mapping cycle of the refrigerator, and the second maintenance priority of the refrigerator is determined according to the leakage degree, so that after-sales personnel can give priority to refrigerators with serious refrigerant leakage according to the second maintenance priority, which is convenient for after-sales personnel to reasonably plan maintenance work, improve the work efficiency of after-sales personnel, and reduce user complaints caused by untimely maintenance.

[0031] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0032] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.
[0033] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.
[0034] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.
[0035] It should be noted that the "multiple" mentioned in this article refers to two or more. "And / or" describes the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.
[0036] Figure 1 The overall structure diagram of a refrigerator after-sales system based on cloud data processing is shown as an exemplary embodiment of the present application. Figure 1 As shown, the refrigerator after-sales system based on cloud data processing may at least include a cloud service end 100 .
[0037] The cloud service end 100 is deployed with a processor and a memory, and a computer program is stored in the memory. When the computer program is executed by the processor, the logical steps corresponding to the method for processing refrigerator operation data recorded in the computer program are implemented to generate refrigerant leakage prompt information when there is a refrigerant leakage in the refrigerator, and send the refrigerant leakage prompt information to a preset after-sales terminal.
[0038] The cloud server can provide multiple users with massive data storage capabilities. Through virtualization, the refrigerators used by users can store and access data just like local hardware, without having to worry about the limitations and management costs of physical devices. Based on this, the cloud server also supports advanced functions such as data backup, recovery, and secure encryption to ensure data security and reliability.
[0039] The refrigerator after-sales system may further include an after-sales terminal 200 .
[0040] The after-sales terminal 200 is connected to the cloud service end 100 for communication, and is used to receive the refrigerant leakage prompt information sent by the cloud service end 100. There may be one or more after-sales terminals 200.
[0041] Among them, after-sales terminals serve as a bridge between enterprises and consumers, directly facing consumers' needs and problems. When consumers encounter problems or need consultation during the use of products, after-sales terminals can respond quickly, provide timely technical support and services, and help consumers solve problems. This direct service method not only improves the efficiency of problem solving, but also enhances consumer satisfaction and trust.
[0042] At the same time, the service quality and attitude of after-sales terminals can directly affect consumers' impression and loyalty to the brand. A professional, efficient and enthusiastic after-sales terminal can leave a good impression on consumers and enhance their trust and sense of belonging to the brand. This trust and sense of belonging will encourage consumers to spread brand reputation more actively and attract more potential consumers to pay attention to and purchase products.
[0043] The refrigerator after-sales system may further include a refrigerator 300 .
[0044] The refrigerator 300 is connected to the cloud server 100 for communication, and is used to send the collected operation data to the cloud server 100. There may be one refrigerator 300 or more.
[0045] It should be explained that the cloud service end 100 of the present application refers to the server end that provides cloud services, which is an important part of cloud computing services. Cloud services are services that obtain the required computing resources and capabilities in an on-demand and easily scalable manner through the Internet. It covers multiple resources such as computing, storage, and network, and provides rich Internet services based on these resources.
[0046] The after-sales terminal 200 realizes data transmission, processing and display through cooperation with the server, providing users with a rich network application experience, such as computer equipment and various mobile devices.
[0047] Figure 2 The overall structure diagram of a refrigerator shown in the exemplary embodiment of the present application. Figure 2 As shown, the refrigerator includes a box body 310 , a freezing compartment 320 may be disposed inside the box body 310 , and a door 330 may be disposed on a side of the freezing compartment 320 .
[0048] It should be noted that the freezing chamber 320 and the cabinet 310 may share a cabinet door 330. The freezing chamber 320 may also be provided with an independent cabinet door 330.
[0049] The refrigerator 300 may further include an operation data collection module 340 .
[0050] The operation data acquisition module 340 may include a first temperature sensor, a second temperature sensor and a third temperature sensor. The first temperature sensor is used to collect the ambient temperature of the refrigerator, the second temperature sensor is used to collect the compartment temperature of the freezing compartment 320, and the third temperature sensor is used to collect the evaporator temperature of the refrigerator.
[0051] It should be noted that the temperature sensor involved in the present application can be a non-contact temperature sensor, for example, an infrared temperature sensor, a sensor that uses infrared radiation to measure temperature. For another example, a radiation thermometer based on the basic law of blackbody radiation can be a temperature sensor made based on any one of the brightness method (such as an optical pyrometer), the radiation method (such as a radiation pyrometer) and the colorimetric method (such as a colorimetric thermometer). The temperature sensor involved in the present application can also be a contact temperature sensor, which moves the sensing part of the temperature sensor to a specified position by setting a controllable robotic arm.
[0052] The operation data acquisition module 340 may also include a frequency acquisition module, which can be used to acquire the compressor frequency.
[0053] The operation data collection module 340 may also include a parameter time collection module for collecting time at each time node and time period.
[0054] In addition, the refrigerator 300 may further include a controller 350. The controller 350 is electrically connected to the operation data acquisition module 340. The controller 350 is used to perform control according to a preset control program.
[0055] Exemplarily, in order to execute the preset control program on the controller 350, a storage module for storing the control program will be set inside the controller 350, and the storage module may include a built-in memory and an external memory, the built-in memory is arranged inside the controller 350, and the external memory is electrically connected to the controller 350. Among them, the external memory and the built-in memory are used for writing and reading the control program, and storing the execution parameters. For example, the built-in memory is generally directly connected to the CPU (Centra lProcessing Unit) corresponding to the controller 350, and its storage capacity is generally small, but because it is directly connected to the CPU, its speed is relatively fast. In this application, the built-in memory is used to store the instructions and data of the current running program and directly exchange information with the CPU. Among them, the built-in memory is composed of many storage units, each unit can store a binary number or an instruction represented by a binary code. The internal memory is composed of a random access memory and a read-only memory. The external memory refers to a memory other than the memory and CPU cache configured by the controller 350. Such a memory can generally still save data after power failure, such as: a hard disk, a floppy disk, an optical disk, a U disk, etc.
[0056] The refrigerator 300 is also provided with a communication module.
[0057] The communication module is connected to the cloud server 100 for communication, wherein the communication module may be a text message module or a WIFI module. Of course, the communication module is not limited to these two types, and this is only an exemplary description without specific limitation.
[0058] At the same time, it should be noted that in the description of the present invention, the orientations or positional relationships indicated by terms such as vertical, up, down, horizontal, etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation and be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.
[0059] In addition, in the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0060] Figure 3 The overall flow chart of a method for processing refrigerator operation data is shown in the exemplary embodiment of the present application. Figure 3As shown, in this application, the method for processing refrigerator operation data includes at least the following execution steps:
[0061] S1. Periodically obtain the operating data of the refrigerator;
[0062] S2. Calculate the time data of the refrigerator during the refrigeration process according to the operation data, where the time data includes at least one of the compressor operation time required for the refrigerator to lower the unit temperature and the defrosting cycle of the refrigerator;
[0063] S3, comparing the time data with the preset mapping data, and determining whether there is a refrigerant leak in the refrigerator according to the comparison result;
[0064] S4. When there is a refrigerant leak in the refrigerator, a refrigerant leak prompt message is generated, and the refrigerant leak prompt message is sent to a preset after-sales terminal.
[0065] Specifically, the present application ensures the reliability and authenticity of the operating data by periodically acquiring the operating data of the refrigerator, so as to timely perform corresponding processing according to the acquired operating data of the refrigerator.
[0066] To illustrate by way of example, the operating data of a refrigerator may be obtained after the refrigerator has been running for a certain period of time, such as every 12 hours, wherein the operating data obtained may be one or more of the operating data at a certain point in time, the operating data at multiple points in time, the operating data for a certain period of time, and the operating data for multiple period of time.
[0067] The time data of the refrigerator during the refrigeration process is calculated according to the acquired operation data, and the time data includes at least one of the compressor operation time required for the refrigerator to lower the unit temperature and the defrost cycle of the refrigerator.
[0068] In one case, when the time data is represented by the compressor operation time required for the refrigerator to lower the unit temperature, the compressor operation time required for the refrigerator to lower the unit temperature is compared with the preset mapping data, and whether there is a refrigerant leak in the refrigerator is determined based on the comparison result.
[0069] For example, under normal circumstances, the compressor operation time required for the refrigerator to lower the unit temperature can be understood as: under normal circumstances, the unit temperature lowered by the refrigerator is 1°C, and the operation time for controlling the refrigerator to refrigerate is 10 minutes. This is used as mapping data, and then the compressor operation time required for the refrigerator to lower the unit temperature actually calculated based on the operation data is compared with the mapping data to determine whether the refrigerator has a refrigerant leak based on the comparison result.
[0070] Alternatively, the mapping data may be set with a certain allowable error based on normal circumstances. For example, under normal circumstances, the unit temperature that the refrigerator lowers is 1°C, and the operating time for controlling the refrigerator to perform refrigeration is 12 minutes, of which the difference of 2 minutes is the allowable error range. The compressor operating time required for the refrigerator to lower the unit temperature under normal circumstances is 12 minutes, which is used as the mapping data. The compressor operating time required for the refrigerator to lower the unit temperature actually calculated based on the operating data is then compared with the mapping data to determine whether there is a refrigerant leak in the refrigerator based on the comparison result.
[0071] In another case, when the time data is represented by a defrost cycle of a refrigerator, the defrost cycle of the refrigerator is compared with preset mapping data, and whether there is a refrigerant leak in the refrigerator is determined based on the comparison result.
[0072] For example, under normal circumstances, the compressor operation time required for the refrigerator to lower the unit temperature can be understood as: under normal circumstances, a defrost cycle of the refrigerator is 8 hours, and this is used as the mapping data. The defrost cycle of the refrigerator actually calculated based on the operating data is compared with the mapping data to determine whether there is a refrigerant leak in the refrigerator based on the comparison results.
[0073] Similar to the previous case, the corresponding mapping data can also be set with a certain error range, which will not be elaborated here.
[0074] In another case, when the time data is represented by the compressor running time required for the refrigerator to lower the unit temperature and the defrost cycle of the refrigerator, for example, in the comparison results of the above two cases, as long as one of the cases determines that there is a refrigerant leak in the refrigerator, it is determined that there is a refrigerant leak in the refrigerator; otherwise, it is determined that there is no refrigerant leak in the refrigerator.
[0075] At the same time, if there is a refrigerant leak in the refrigerator, a refrigerant leak prompt message is generated and sent to a preset after-sales terminal. For example, the refrigerant leak prompt message may include the model of the refrigerator and user information, wherein the user information may be obtained from the after-sales record sheet recorded when the refrigerator is sold, and the user information may include the user's identity information, contact information, and the refrigerator delivery address.
[0076] During actual use, after-sales personnel can quickly find the refrigerant material usage specifications of the corresponding refrigerator according to the refrigerator model. They can also inform the user in advance through the user's identity information and arrange a visit time with the user. At the same time, they can find the refrigerator with refrigerant leakage according to the refrigerator delivery address and perform after-sales maintenance work.
[0077] Through the above implementation, based on the periodically acquired operating data of the refrigerator, the time data of the refrigerator during the refrigeration process is calculated, so as to judge whether there is a refrigerant leak in the refrigerator according to the comparison result of the time data and the mapping data, and generate a refrigerant leakage prompt message when there is a refrigerant leak in the refrigerator and send it to the preset after-sales terminal, so that the present application can identify the refrigerator with refrigerant leakage according to the operating data of the refrigerator, and after the after-sales terminal receives the refrigerant leakage prompt message, it is convenient for the after-sales personnel to take timely response measures, thereby reducing user complaints.
[0078] Figure 4 FIG. 1 is a schematic diagram of the overall flow of a method for processing refrigerator operation data shown in another exemplary embodiment of the present application. Figure 4 As shown, in some embodiments of the present application, based on the above embodiments, in the step of comparing the time data with the preset mapping data and determining whether there is a refrigerant leak in the refrigerator according to the comparison result, the following contents may be specifically included:
[0079] If the comparison result shows that the compressor operation time required for lowering the unit temperature of the refrigerator is greater than the preset mapping time, and / or the defrost cycle of the refrigerator is greater than the preset mapping cycle, it is determined that there is a refrigerant leak in the refrigerator.
[0080] Specifically, in one case, in the process of determining whether there is a refrigerant leak in the refrigerator, if the compressor running time required for the refrigerator to lower the unit temperature is greater than the preset mapping time, it indicates that there is a refrigerant leak in the refrigerator; in another case, if the defrost cycle of the refrigerator is greater than the preset mapping cycle, it also indicates that there is a refrigerant leak in the refrigerator; in yet another case, if the compressor running time required for the refrigerator to lower the unit temperature is greater than the preset mapping time, and the defrost cycle of the refrigerator is greater than the preset mapping cycle, it also indicates that there is a refrigerant leak in the refrigerator; that is to say, as long as any of the above three situations occurs, it can be determined that there is a refrigerant leak in the refrigerator.
[0081] Through the above-mentioned implementation mode, the present application combines two judgment methods to judge the refrigerator with refrigerant leakage, which can improve the accuracy and reliability of the judgment result and improve the work efficiency of after-sales personnel.
[0082] Figure 5 FIG. 2 is a schematic diagram of an overall flow chart of a method for processing refrigerator operation data according to another exemplary embodiment of the present application. Figure 5As shown, in some embodiments of the present application, based on the above embodiments, before judging whether there is a refrigerant leak in the refrigerator, it is determined whether there is a sensor failure in the refrigerator based on the operating data of the refrigerator. If there is a sensor failure, the specific sensor fault code is sent to the after-sales terminal. At the same time, the model information and user information of the refrigerator are also sent to the after-sales terminal. After-sales personnel can come to the door for replacement and repair based on the sensor fault code, the model information and the user information of the refrigerator.
[0083] Through the above implementation, after-sales personnel can repair a refrigerator with a sensor failure before the refrigerator leaks refrigerant, so as to reduce user complaints caused by the inability to collect corresponding operating data through the sensor when the refrigerator leaks refrigerant.
[0084] In some embodiments of the present application, based on the above embodiments, the method for processing refrigerator operation data also includes: determining the ambient temperature and compartment temperature of the refrigerator according to the operation data; when the difference between the ambient temperature and the compartment temperature is greater than a preset temperature difference threshold, adding the preset time mapping value to the mapping time to obtain an updated mapping time.
[0085] For example, under normal circumstances, the refrigerator performs refrigeration control according to the preset mapping time in the program setting, but in some specific cases, due to the hot climate, when the load (for example, food that needs to be refrigerated) is placed in the refrigerator, the refrigeration control of the refrigerator needs to take more time than normal to achieve the refrigeration effect of the load. For example, under normal circumstances, the difference between the ambient temperature and the compartment temperature is between 0°C and 40°C; in the hot summer, the ambient temperature is 40°C, the compartment temperature is minus 10°C, and the difference is 50°C. In this case, the mapping time needs to be increased by 30 minutes to ensure the normal refrigeration effect of the load. Of course, the data in the above example is only for illustrative purposes and is not specifically limited. At the same time, after the mapping time is updated, the refrigerant leakage of the refrigerator is determined according to the updated mapping time.
[0086] It should be noted that the update of the mapping time is only used in the processing of the operating data obtained in the current cycle. When judging the refrigerant leakage based on the obtained operating data in other cycles, it is necessary to re-judge based on the difference between the ambient temperature and the compartment temperature to decide whether the mapping time needs to be updated. If not, the default mapping time in the control program is maintained to execute the corresponding judgment step.
[0087] Through the above implementation, in some specific cases, in order to ensure the normal refrigeration effect of the load, the refrigeration control time of the refrigerator needs to be longer than the refrigeration control time under normal circumstances. Therefore, the mapping time is adjusted by a certain increment to reduce the occurrence of misjudgment or misjudgment of refrigerant leakage. Further, when judging a refrigerator with refrigerant leakage, the accuracy and reliability of the judgment result can be improved, thereby improving the work efficiency of after-sales personnel.
[0088] In some embodiments of the present application, based on the above embodiments, in the step of calculating the time data of the refrigerator refrigeration process according to the operating data, the following contents are specifically included: determining the compartment temperature of the refrigerator according to the operating data; calculating the temperature difference between the compartment temperature and the preset target temperature, and obtaining the refrigeration time consumed by the refrigerator to drop from the compartment temperature to the target temperature, and determining the compressor operation time required for the refrigerator to lower the unit temperature according to the ratio of the refrigeration time to the temperature difference.
[0089] For example, the compartment temperature determined according to the operating data is 0°C, and the target temperature is minus 6°C, so the calculated temperature difference is 6°C. If the refrigeration time taken for the refrigerator to drop from the compartment temperature to the target temperature is 60 minutes, the ratio of the refrigeration time to the temperature difference is 6, and the corresponding compressor operation time required for the refrigerator to lower the unit temperature is 6 minutes.
[0090] Through the above implementation, the control program can realize the corresponding calculation process according to the clear input parameters and output parameters, so as to obtain the basis for judging the refrigerant leakage.
[0091] It should be noted that the multiple calculation processes in the above-mentioned embodiments can be implemented by multiple calculation modules set inside the refrigerator controller to generate corresponding calculation data, or can be implemented by multiple calculation modules set on the cloud server connected to the refrigerator. At the same time, different calculation modules can be composed of different arithmetic operation circuits, and for the arithmetic operation circuit, it can be a basic integrated operational amplifier circuit. For example, the arithmetic operation circuit can be a digital adder circuit, the arithmetic operation circuit can be a digital subtractor circuit, the arithmetic operation circuit can be a digital multiplier circuit, the arithmetic operation circuit can be a digital divider circuit, and so on. For the calculation modules of each calculation step in the present application, the corresponding arithmetic operation circuit can be adopted according to the specific usage scenario.
[0092] In some embodiments of the present application, based on the above embodiments, in the step of calculating the time data of the refrigerator refrigeration process according to the operating data, the following contents are specifically included: determining the evaporator temperature of the refrigerator according to the operating data; determining the defrost cycle of the refrigerator according to the change law of the evaporator temperature.
[0093] For example, the operation data of the refrigerator within a period of time is obtained, and during this period of time, the variation pattern of the evaporator temperature is determined according to the operation data of the refrigerator. For example, the evaporator temperature corresponding to continuous time points is obtained, taking one second as an example, and the evaporator temperature is collected every 1 second through the temperature acquisition module set on the refrigerator. Since the temperature change of the evaporator during the refrigeration control process of the refrigerator is periodic, the corresponding cycle of the refrigeration control and the defrosting cycle of the refrigerator can be estimated from the continuously collected evaporator temperature.
[0094] Figure 6 FIG. 1 is a schematic diagram of a tree diagram structure of a mapping data determination process shown in an exemplary embodiment of the present application. Figure 6 As shown, in some embodiments of the present application, based on the above embodiments, the method for processing refrigerator operation data also includes at least the following contents: determining the ambient temperature and compressor frequency of the refrigerator according to the operation data, and determining the ambient temperature range corresponding to the ambient temperature, and determining the compressor frequency range corresponding to the compressor frequency; determining mapping data according to the ambient temperature range and the compressor frequency range.
[0095] Specifically, by way of example, through the preset mapping table and the data relationship setting in the table, the mapping data to be compared with the time data can be quickly found. For example, the ambient temperature interval is divided into the first ambient temperature interval, the second ambient temperature interval and the third ambient temperature interval; the compressor frequency interval is divided into the first compressor frequency interval, the second compressor frequency interval, the third compressor frequency interval and the fourth compressor frequency interval. Each interval of the ambient temperature interval is set corresponding to a plurality of compressor frequency intervals, and the mapping time and mapping period corresponding to each compressor frequency interval under one ambient temperature interval are different. The specific setting method can be differentiated and set according to different regions.
[0096] Through the above implementation mode, the mapping data of the present application is divided into data of ambient temperature range and compressor frequency range, and specific mapping data is retrieved and determined, which is convenient for quickly finding mapping data for comparison with time data, thereby improving the execution efficiency of the method for processing refrigerator operation data.
[0097] In some embodiments of the present application, based on the above embodiments, in the step of calculating the time data of the refrigerator refrigeration process according to the operating data, at least the following contents are also included: when the refrigerator is in an open-door state, the compressor operation time required for the refrigerator to lower the unit temperature is reset, and when the refrigerator is in a closed-door state, the compressor operation time required for the refrigerator to lower the unit temperature is calculated according to the operating data.
[0098] Specifically, to calculate the compressor running time required for the refrigerator to lower the unit temperature, the operating data of the time period when the refrigerator is in the closed state is needed to calculate. If the refrigerator opens its door within the corresponding time, it means that the user may be refrigerating items in the storage area, and the placement and removal of refrigerated items may affect the calculation of the compressor running time required for the refrigerator to lower the unit temperature. For example, the compartment temperatures corresponding to the presence and absence of load in the refrigerator are different. For another example, after a load with a temperature much higher than the refrigerator compartment temperature is placed in the refrigerator, the compartment temperature will change significantly. Therefore, after the refrigerator corresponding to the present application opens its door, the compressor running time required for the refrigerator to lower the unit temperature is reset to zero. At the same time, after the refrigerator is in the closed state, the compressor running time required for the refrigerator to lower the unit temperature is recalculated based on the refrigerator compartment temperature, ambient temperature and refrigeration time.
[0099] Through the above implementation, the calculation of the compressor operation time required for the refrigerator to lower the unit temperature needs to be limited to a certain time period when the refrigerator is closed, thereby eliminating the change in operating data caused by opening the refrigerator door, thereby reducing the probability of the judgment result of refrigerant leakage being affected.
[0100] In some embodiments of the present application, based on the above embodiments, the step corresponding to generating refrigerant leakage prompt information when there is a refrigerant leakage in the refrigerator may also include at least the following contents: calculating the first difference between the compressor operation time required to lower the unit temperature of the refrigerator and the mapping time, and determining the leakage degree of the refrigerant leakage according to the first difference; determining the first maintenance priority of the refrigerator according to the leakage degree, and the first maintenance priority is used to determine the refrigerant leakage prompt information.
[0101] For example, the degree of refrigerant leakage is divided according to the difference between the compressor operation time required to lower the unit temperature of the refrigerator and the mapping time. For example, it is divided into three levels. The difference corresponding to the first level is large, indicating that the degree of refrigerant leakage is very serious; the difference corresponding to the second level is moderate, indicating that the degree of refrigerant leakage is serious; the difference corresponding to the third level is small, indicating that the degree of refrigerant leakage is slight.
[0102] For example, the difference range corresponding to the first level can be 20min to 30min, the difference range corresponding to the second level can be 10min to 20min, and the difference range corresponding to the third level can be 0min to 10min; if the first difference between the compressor operation time required to lower the unit temperature of the refrigerator and the mapping time is 25min, it means that the refrigerant leakage of the corresponding refrigerator is very serious and needs to be handled by after-sales personnel as a priority; if the first difference between the compressor operation time required to lower the unit temperature of the refrigerator and the mapping time is 5min, it means that the refrigerant leakage of the corresponding refrigerator is slight, and after-sales personnel can handle other refrigerators with high refrigerant leakage priorities before handling refrigerators with low refrigerant leakage priorities. Of course, the above data is only for illustrative purposes and is not specifically limited.
[0103] Through the above implementation, the leakage degree of the refrigerant leakage is determined based on the first difference between the compressor operation time required for lowering the unit temperature of the refrigerator and the mapping time, and the first maintenance priority of the refrigerator is determined according to the leakage degree, so that after-sales personnel can give priority to refrigerators with serious leakage degree of refrigerant leakage according to the first maintenance priority, which is convenient for after-sales personnel to reasonably plan maintenance work, while improving the work efficiency of after-sales personnel and reducing user complaints caused by untimely maintenance.
[0104] In some embodiments of the present application, based on the above embodiments, the step corresponding to generating refrigerant leakage prompt information when there is a refrigerant leakage in the refrigerator may also include at least the following contents: calculating the second difference between the defrost cycle and the mapping cycle of the refrigerator, and determining the leakage degree of the refrigerant leakage according to the second difference; determining the second maintenance priority of the refrigerator according to the leakage degree, and the second maintenance priority is used to determine the refrigerant leakage prompt information.
[0105] For example, the degree of refrigerant leakage can also be divided according to the second difference between the defrost cycle and the mapping cycle of the refrigerator. Similarly, it can also be divided into three levels. The difference corresponding to the first level is large, indicating that the degree of refrigerant leakage is very serious; the difference corresponding to the second level is moderate, indicating that the degree of refrigerant leakage is serious; the difference corresponding to the third level is small, indicating that the degree of refrigerant leakage is slight.
[0106] Similar to the above embodiment, the leakage degree of the refrigerant leakage is determined according to the first difference between the compressor operation time required to lower the unit temperature of the refrigerator and the mapping time, and will not be described in detail here.
[0107] Through the above implementation, the leakage degree of the refrigerant leakage is determined based on the second difference between the defrost cycle and the mapping cycle of the refrigerator, and the second maintenance priority of the refrigerator is determined according to the leakage degree, so that after-sales personnel can give priority to refrigerators with serious leakage degree of refrigerant leakage according to the second maintenance priority, which is convenient for after-sales personnel to reasonably plan maintenance work, improve the work efficiency of after-sales personnel, and reduce user complaints caused by untimely maintenance.
[0108] It should be noted that the above two methods of determining priority can be set either individually or simultaneously, and the one with the highest calculated priority shall prevail.
[0109] For example, when set at the same time, the priority is determined as the first level based on the first difference between the compressor running time required for lowering the unit temperature of the refrigerator and the mapping time, which means that the refrigerant leakage of the corresponding refrigerator is very serious; however, the priority is determined as the second level based on the second difference between the defrost cycle of the refrigerator and the mapping cycle, which means that the refrigerant leakage of the corresponding refrigerator is serious; at this time, the priority determined by the first difference between the compressor running time required for lowering the unit temperature of the refrigerator and the mapping time is the final priority.
[0110] In some embodiments of the present application, based on the above embodiments, the method for processing refrigerator operation data may also include at least the following contents: determining the sleep time of the refrigerator according to the operation data; when there is a refrigerant leak in the refrigerator, calculating the difference between the sleep time and the preset operation replenishment time, and sending the difference as the updated sleep time to the refrigerator.
[0111] It should be noted that the refrigerator of the present application can be a variable frequency refrigerator, so that after reaching the target refrigeration temperature, the refrigerator performs the auxiliary refrigeration work of the corresponding refrigeration device at a lower power, and the time of execution at a lower power can be understood as the sleep time of the refrigerator corresponding to the lower power.
[0112] To illustrate by way of example, if the refrigerator determines that there is a refrigerant leak, while sending a refrigerant leak prompt message to the after-sales terminal, the cloud server calculates the difference between the sleep time and the preset running supplement time, and sends the difference as the updated sleep time to the refrigerator, thereby reducing the sleep time corresponding to the auxiliary refrigeration work of the corresponding refrigeration device performed at lower power by the refrigerator.
[0113] For example, when there is no refrigerant leakage in the refrigerator, the refrigerator executes normal refrigeration control time as the first time. When there is a refrigerant leakage in the refrigerator, if the refrigerator still executes normal refrigeration control time as the first time, it will cause the refrigerator to fail to meet the refrigeration requirements. Therefore, the refrigeration requirements of the refrigerator can be ensured by extending the normal refrigeration control time.
[0114] Through the above implementation, when there is a refrigerant leak in the refrigerator, the sleep time of the refrigerator is reduced so that the time corresponding to the refrigerator executing normal refrigeration control can be extended to a certain extent, thereby ensuring that the refrigerator can achieve a normal refrigeration effect in a short time, thereby buying time for after-sales personnel to arrive at the scene.

It should also be noted that in some alternative implementations, the functions marked in the box can also occur in a different order from the order marked in the drawings. For example, two boxes represented in succession can actually be executed substantially in parallel, and they can sometimes be executed in the opposite order, depending on the functions involved.
